  8. Evaluation Your grade will be based on: • 5 Homeworks • 4 Machine Problems • 1 Final Project • 2 Exams • 1 Final • Occasional Unannounced Quizzes

  9. Course Goals I ECE291 bridges the gap between your logic classes and programming courses through assembly-level programming of a real (80x86) computer

  10. Course Goals II • You will become proficient in assembly-level programming • You will learn to organize large programs. • You will learn how to interface to hardware

  11. Course Overview • Course Syllabus • Lecture, Exam, Homework, MP Schedule • Lab Staffing Schedule

  12. Today’s Topics • History of computing • Rapid changes (Moore’s Law) • Review of previous classes

  13. A very short history and historical perspective

  14. 1642 Blaise Pascal invents his mechanical calculator (counting device)

  15. 1830 • Charles Babbage’s “Difference Engine” • First steam-powered “Analytical Engine”

  16. 1880’s • John H. Patterson’s Mechanical cash register (NCR) • First applications for computing devices

  17. 1930’s Claude Shannon suggests use ofthe binary system for usewith electronic circuits

  18. 1940’s John Von Neumann proposes reconfigurable computing by storing programs in memory

  19. 1940’s – 1950’s First electronic computers • Vacuum tubes & mechanical relays: UNIVAC, ENIAC • 30 tons • 150 Kwatts • 80 bytes of memory

  20. 1940’s – 1950’s ILLIACMetze et. al. play Illinois fight song on accumulator bit – first computer music
